RADIATOR.

Application filed September 8, 1925. Serial No. 55,104.

The invention relates to radiators and more especially to an improvedradiator construction involving particularly the connection between thefiller neck and radiator shell or casing. According to this invention afloating connection between the filler neck and radiator shell isprovided, together with means for adjusting the connection, tocompensate for differences in size in the radiator parts and tocompensate further for wear, whereby objectionable rattling iseliminated, and a proper union between the parts constantly assured.

The invention has also among its objects to simplify, render moreefficient, and improve generally devices of this general character, andthese as well as other objects, advantages, and novel details ofconstruction7 will be made more apparent as this description proceeds,especially when considered in connection with the accompanying drawingswherein Figure 1 is an elevation of a radiator constructed in accordancewith my invention, certain parts being broken away to show interiorconstruction, and

Figure 2 is a side elevation of the radiator shown partly in section.

Referring now particularly to the drawings wherein like referencecharacters indicate like parts, it'will be noted that there isillustrated a radiator core 10 which has formed therewith and as a partthereof, upper and lower headers or tanks 11 and 12. This coreconstruction is arranged in a radiator casing 13 of the usualconstruction, surrounding the same in the customary manner.

The core may be secured within the casing in any suitable manner but theconnection therebetween is herein shown as consisting ot bolts 14passing upwardly through the bottom of casing 13 and threadedly engaginglugs 15 arranged within the bottom tank 12. The bolts 14 are preferably,although not necessarily, spaced equi-distant of the vertical center ofthe radiator and interposed between the bottom wall of tank 12 and thebottom of casing 13 is a strip of yieldable material 16. In this manneran anti-rattling connection is assured between the core and casing atthis point and a slight relative movemnt between the core and casing ispermitte A filler neck 17 projects upwardly from upper header 11 andVextends through an opening 18 formed in casing 13. Fille-r neck 17 isprovided, adjacent that portion which crit-ends through casing 13, witha ycircumferential shoulder 19. The greatest diameter of filler neck 17is slightly smaller than the diameter of opening 18, whereby the fillerneck is slightly spaced and loosely engages opening 18.

Arranged upon circumferential shoulder 19 of filler neck 17 is acircumferential yielding member 20 formed preferably of rubber or othersimilar material. This filler member 20 is designed to extend betweenller neck 17 and the wall of aperture 18 and to center the filler neckwith reference to the opening 18. A nut 21 in the form of a collarthreadedly engages filler neck 17 and iS adapted to be screwed downagainst yieldable member 20 for the purpose of holding the same firmlyagainst shoulder 19 and for compressing the same to expand itcircumferentially and to cause it to irmly engage the wall of opening18.

With a structure of this character it will be readily apparent thatwhile a yieldable and floating connection is provided between the fillerneck and the radiator casing, that any rattling at this point ofconnection may be positively prevented as the filler member 20 may becompressed more or less as the occasion demands by means of nut 21 tocompensate for any wear of the parts or for any variance in size. W'iththe yieldable member 20 irmly engaging the filler neck and the wall ofaperture 18 the filler neck will be centered with reference to theopening to prevent any met-al to metal contact andi a limited amount ofrelative movement between the core and the casing is permitted, whichwill tend to compensate Y for stresses imparted to the radiator.

While an embodiment of the invention has been illustrated and describedin some detail it will be readily apparent that various changes andlmodificati ons may be resorted to without departing from the spirit andscope of this invention, and to this end reservation is made to makesuch changes as may come within the purview of the accompanying claims.

Wvhat claim as my invention is:

1. In a radiator, a. casing, a core provided with a iller neck engagingan opening formed in said casing, anexpansible member carried by saidfiller neck and disposed radially between said filler neck and casingand means adjustable on said filler neck for expanding said memberradially.

2. In a radiator, a casing provided with an opening, a core formed witha filler neck having a floating connection with said opening, ayieldable centering member interposed between said liller neck andcasing, and means on said neck for clamping said yieldable member toradially expand the same.

. 3. Ina radiator, a casing provided with an opening, a core formed witha iiller neck engaging said opening, a yieldable centering memberinterposed between said filler neck and casing, and a nut threaded onsaid filler neck and engaging saidyieldable member for expanding thesame.

4. In a radiator, a casingprovided with an opening, a core formed With aiiller neck engaging saidopening, a circumferential shoulder formed onsaid iillerneck, a yieldable member engaging said shoulder, and aclamping nut threaded on said iiller neck for coinpressing saidyieldable member, for the purpose set forth.

` 5. A radiator comprising a casing, an element Within theI casingprovided-y with a iller neck extending Within an opening in the casingand spaced from the innerwall of said opening, a yieldable memberforming a connection between the iiller neck and casing to absorbrelative vibrations therebetw en, said iiller neck being provided with ashoulder forminga support for the said yieldable member, and meansact-ing on said; yielding member for distorting the samelaterallybetween the said shoulder and said means.

In testimony whereof aiix mv signature.
